Few more recommendations:

• fix all the previous comments and mark them resolved if you think it is done
• link all the issues that this PR solves into the Development tab on the right
• if you want a review from somebody, link them as reviewers in Reviewers tab on the right - if you want to have your new changes re-reviewed, click on request review next to the reviewer so that they are notified
• ensure that all checks pass before requesting another review (currently clang-tidy formal check fails, try running run-clang-tidy -p [YOUR_BUILD_DIR] (with -fix flag) to see the errors locally

Also, add the new tests binary into sonar automation (sonarqube.yml).
Follow the flow of mechanics.micromechanics.tests inside the file, add mechanics.physicell.tests, the sources and tests under --define sonar.sources and --define sonar.tests
